The biggest difference between the existing HI98129 and the Groline HI98131 is that the Groline features the Quick Cal Mode, which allows you to calibrate the pH and EC\/TDS with a single solution. \u003c\/p\u003e\n\u003cp\u003eThe HI98131 is a slim, lightweight, and waterproof pocket sized meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature. The meter operation is simplified with two buttons. One is used for on\/off and for calibration while the other is used to switch between the measurement modes. The HI98131 has advanced features including a selectable EC to TDS conversion factor (0.5 - 500 ppm and 0.7 - 700 ppm).\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe HI98131 GroLine tester features a large multi level LCD which displays both pH, EC or TDS and temperature readings simultaneously. The pH readings are displayed with a 0.01 resolution and with an accuracy of +\/-0.05 pH, while the EC and TDS readings are displayed with a 0.01 mS\/cm and 10 ppm (mg\/L) resolution and 2% full scale accuracy. The EC range of the HI98131 is from 0.01 to 6.00 mS\/cm and TDS is from 0 to 3000 ppm using a 0.5 conversion factor. The HI98131 also offers the option to use a \u003c\/span\u003e\u003cspan\u003e0.7 (700 ppm) \u003c\/span\u003e\u003cspan\u003eEC to TDS conversion factor. An exposed temperature sensor allows for rapid temperature compensated measurements of EC and TDS. The LCD screen has indicators for calibration status and stability. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.  The HI98131 is a versatile pocket meter designed for hydroponics, greenhouse and agriculture applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSimplified one button calibration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eOne or two point pH calibration is automatic to a pre-programmed buffer set (4.01, 7.01 and 10.01) or single point pH and EC calibration with the Hanna Quick Cal calibration solution.
